Y To dll whomz't may concern:

Be it known that I, PIUS F. KILLIAN, a citizen of the United States, residing at Owensboro, in the county of Daviess' and State of Kentucky, have invented certain new and useful Improvements in Acetyleiie- Gas Generators, of which the following is a specification.

This invention relates to acetylene gas generators. and more particularly that class of such generators which are designed to be located within the ground and to generate gas in sufiicient quantities for use in homes and other buildings andthe invention aims generally to provide a generator of this class which will be automatic in its operation, highly efficient in the generation of the gas, and entirely safe to use.

It is one aim of the invention to provide a novel means for feeding the carbid to the generating chamber in predetermined quantities suflicient to generate the desired quantity of gas without any likelihood of the a creation of too high pressure,the feeding device being adjustable so that the amount of the charge may be varied to suit the conditions under which the generator is to be employed.

In the accompanying drawings:

Figure 1 is a vertical sectional view through the generator embodying'the present invention;

Fig. 2 is a detail vertical sectional view through the carbid ing device.

The casing of the generator is indicated in general by the numerall and the same is preferably cylindrical and may be of any desired height and circumferencaand this casing at its lower end is closedby-a bottom 2 riveted or otherwise secured in place. The top of the casing is normally closed by a cover 3. Arranged concentrically within the casing 1 is a casing section or drum 6 which is preferably of frusto-conical form and which at its lower end is of the same chamber and the feeddiameter as the interior of the casing andis' secured thereto; as at 7, the space between the wall of the casing and the wall of the casing section 6 constituting a water chamber, indicated by the numeral 8. The casing,

carbid chamber is provided exteriorly with a circ-umscribing reinforcing band 12, and secured to this band is the top for the said carbid chamber, indicated by the numeral 13, the said top being provided preferably.

centrally with a filling opening 14 having a removable closure 15. The portion 9 of the carbid chamber is fitted into the smaller or upper end of the casing section 6 with the lower edge of the reinforcing band 12 restingupon the'upper edge of the said casing section 6, as clearly shown in Fig. 2 of the drawings.

The carbid is delivered from the carbid chamber through the open lower end of the discharge spout 11 and in order that the discharge of carbid from the said spout-may be regulated by dividing the carbid into charges of predetermined 'quantities, there is provided a feeding device which will now be described. The device just mentioned comprises a valve having side walls 16 and a bottom 17 which extends between the loweredges of the said side walls, the valve being open at its forward side and closed at its rear side, as indicated at 18, the walls 16, bottom 17, and closed side 18, forming a pocket 19 of a suitable size to receive the desired quantity of carbid to constitute a single charge. Rearwardly of the closed rear side 18 of the pocket the valve is weighted, as at 20, for a purpos'e .to be present'l yexplained. Arms 21 extend upwardly from the sidewalls 16 and are pivotally connected at their u'pperend, as at 22, to the opposite sides 05 the discharge spout 11 at the upper-end thereof, It will now beunderstood that normally the valve member will, by reason of its weighted "portion 20,

tend to assume approximately the position shown in full lines'in Fig. 2 of'the drawings, and in order that the position of the valve when at rest may, be varied so as to 'vary the amount of carbid forming the charge to be delivered by the valve, a set screw 23 is threaded through a lug 2st upon the upper side of the weighted portion 20 ofthe valve and has one end projecting in position for abutment against the lower end of the discharge spout 11, there being a set nut threaded upon the set screw or the purpose of holding the same at adjustment. Extending transversely between the side walls 6 of the pocket of the valve member is a cutoff plate 26 which'is preferably I curved from end to end on an arc concentric to the pivots for the said valve member and this cut-ofi plate in all positions of the valve member lies relatively close to the open lower end of the discharge spout 11, the plate'being designed to regulate the dis charge of carbid into the pocket in the valve in a manner which will presently be explained. The actuating member for the valve member-is in the nature of a rod 27 which has a curved lower end pivotally connected, as at 28, with the forward end of the cut-off plate 26. Extending between the upper and lower ends of the carbid chamber and forming a guide for-the actuating rod 27, is a sleeve 29, the sleeve being of such dimensions as to permit of movement of the rod 27 to all of the positions shown in the drawings, and particularly Fig. 2 thereof, and at its upper or smaller end being interiorly of such diameter as to permit of passage of gas into the gas bell which surrounds the' upper end of the casing section 6, as will be presently more specifically described.

The gas bell heretofore referred to comprises a hollow cylindrical body 43 closed at its top as at 4A and open at its bottom, the said body being provided at intervals wlth vertically extending lips 45 upon its exterior surface which lips are preferably substantially triangular in horizontal section so that their edges may slidably engage the inner surface of the wall of the casing 1 with minimum friction, the gas bell being -in this manner guided in its raising and lowering movements. In order that the gas bell may be readily removed. from the easing 1 whenever necessary, there is provided a handle in the nature of a pipe 46 connected at one end by an elbow L7 to the top 44 of the bell at one side thereof and at a dia- 'metrically opposite point being connected at its other end to the said top by a T-coupling 48, the lower branch of the coupling communicating with the interior of the gas bell and a plug 49 being removably fitted into the upper branch of the T whereby air maybe admitted into the bell prior to lifting the same from the casing and thereby destroy the partial vacuum which would otherwise be created due to the submergence of the lower end of the bell into the 2 water contained in the chamber 8. In order to suitaliily weight the end of the bell the same is provided with a circumscribing band 50.

By reference to Fig. 2 of the drawings it will be observed that the inner end of the cut-off plate 26 terminates short of the closed end 18 of the pocket and it will further be observed that the said plate extends forwardly beyond the open end of the pocket. It will also be apparent by reference to Fig. 2 that the said inner end of the cut-off plate 26 in the normal position of the valve terminates approximately immediately below the center of the discharge end of the spout 11 so that in this position of the valve a suitable quantity of carbid may flow from the spout around the said inner end of the cut-off plate and collect within the pocket. Assuming that a quantity of gas has been generated and subsequently consumed, it will be understood that the bell 43 will lower and as it does so it will engage the upper end of the rod 27 and will move the said rod downwardly, In such movement of the rod the valve will be tilted or swung to approximately the dash line position shown in Fig. 2 whereupon the earbid charge contained within the pocket will be dropped into the water in the generating chamber and a quantity of gas will then be generated and entering the bell will cause the same to rise in the well-known manner. Of course, as the valve is moved from the position shown in full lines to the position slnnvn in dash lines the cut-off plate 2% will prevent the discharge of carbid from the discharge spout 11. From the generator the generated gas is conducted to the distributing main through a purifying device includ ing a pipe section 51 which is led at its lower end through the side of the casing 1.

Having thus described the invention, what is claimed as new is:

1. A gas generator including a oarbid chamber having a discharge spout, and a valve member for controlling the discharge ofcarbid from the said spout, the said valve member comprising a pocket having a bottom and spaced sides and open at one end and closed. at the other end, means pivotally supporting the pocket for swinging movement beneath the said spout, means for moving the said pocket, a cut-oil plate extending between the sides of the pocket and at its in'nerend end of the pocket, the said plate extending relatively close to the end of the discharge spout, means tending to hold the valve mem' her in position beneath the discharge end of the said spout, and adjustable means for limi to receiving position.
